Level: Basic
The footer is prime real estate that's often neglected, even though it's one of the last things a visitor sees before deciding whether to leave or explore further.
Use the Footer for Secondary, Not Primary, Navigation
The footer is a good home for less frequently needed links — policies, sitemaps, secondary resources — that would clutter the primary navigation.
Organize Footer Links Into Clear Categories
A large footer benefits from the same clear grouping and labeling principles as primary navigation, rather than presenting a single undifferentiated list of links.
Don't Overload It Purely for SEO Purposes
A footer stuffed with excessive links purely to create internal linking opportunities tends to hurt the user experience more than it helps.
Next step: Use the Website Links Count Checker to check how many links your footer currently contains and whether they're organized clearly enough to actually be useful.
